Vermont Gage 111324750 Class Zz Plus Plug Gage 0.2475 in

Product Description

The VERMONT GAGE 111324750 is a Class ZZ Plus plug gage designed for precision dimensional inspection of hole diameters. Manufactured from tool steel with a 10 microfinish surface, this gage measures a nominal diameter of 0.2475 inches with a tolerance of 0.0002 inches. It conforms to ASME B89.1 standards and ships with a Certificate of Accuracy carrying NIST traceability. The overall length is 2.0 inches. Quality control technicians, machinists, and metrology personnel use this type of gage in production and inspection environments where close-tolerance hole verification is required.

This plug gage is suited for go inspection of machined bores, drilled holes, and similar features in manufacturing and fabrication settings. It is also appropriate for setting and verifying micrometers, vernier calipers, and other measuring devices requiring a reference standard at this diameter. Applications span general metalworking, aerospace, automotive, and precision machining shops where consistent hole acceptance criteria must be met at the 0.2475 inch nominal size.

Key Features

• Class ZZ Plus tolerance class per ASME B89.1 for reliable go inspection
• 0.2475 inch nominal measurement diameter with 0.0002 inch tolerance
• 10 microfinish surface for accurate, repeatable contact
• Tool steel construction for durability in production inspection use
• Includes Certificate of Accuracy with NIST traceability
• Overall length of 2.0 inches for standard handle compatibility

Compatibility

Designed for go inspection use with micrometers, verniers, and other measuring devices requiring a 0.2475 inch diameter reference standard. Suitable as a drop-in replacement or calibration reference wherever a Class ZZ Plus plug gage at this nominal diameter is specified per ASME B89.1.

Installation Notes

Plug gages are handled and used by qualified inspection or metrology personnel. Store the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Handle with clean, dry hands or cotton gloves to avoid transferring oils that can affect measurement accuracy. Follow your facility calibration schedule and ASME B89.1 guidelines for periodic reverification of the gage.
